  • RE: BQ27541-V200: Temperature of chemical ID

    Hello Tom For very low temperature operation, there is additional information required. There are online tools to help tweak the chemistry data. Please see GAUGEPARCAL and GPCRB tools for more information

  • RE: BQ40Z80: CHEMID for PANASONIC NCR2070C

    Grandaphi, Currently this cell does not exist in our database. I was waiting to reply hoping someone from the community could have a better answer. I do suspect you will find a match to an already existing chemID. As i assume you are doing please use…

  • RE: BQ4050: Shut off learning feature

    Michael, The gauge will constantly be learning. The 6 cycles can be done outside of the system and just collected on the bench. They are used to establish the "EDV" end voltage points. The procedure to follow is located here https://www.ti.com…

  • RE: BQ40Z60: How to know if my cell is original based on learning cycle and data log?

    Widji, When using a new battery the best thing to do it to run a match using our GPC online tool https://www.ti.com/tool/GAUGEPARCAL . If the ID you used is in the list the you should be ok to proceed with the learning. The sysrate log file you provided…

  • BQ34110: Which voltage parameters are for stack voltage, and which are for cell voltage?

    TI Thinks Resolved
    Part Number: BQ34110 Other Parts Discussed in Thread: GAUGEPARCAL The documentation is very lacking regarding which voltage parameters need to be set per CELL and which are set per STACK. You cannot use the default values (as one suggested) because those…

  • RE: BQ27220: about BQ27220 config file and program

    Hi, 1. Registers show the status of the device, no need to configure. 2. Actual values in the application should be used for data memory, not default value. 3. Correct, you can use the Calibration in bqStudio to perform calibration. 4. You can use GPC…

  • RE: BQ76930EVM: How to configure BQ76930EVM for 8 cell operation?

    Hi First, It sounds like you have the cells selected appropriately. The gauge on the BQ76930 EVM is the BQ78350-R1A. Depending on when the board was produced it may have an earlier version. You can load the latest version from the product folder and load…

  • RE: BQ34Z100-G1： True FCC becomes smaller

    There are two issues, which are not independent from each other: 1. The gauge doesn't predict temperature correctly for your system. Your battery heats up to around 80deg.C during discharge. The gauge doesn't predict temperature that high and therefore…

  • RE: BQ27750: Re-Open: Question regarding remaining energy in cWh

    Resolved
    Marcel, I would not say the jumps are not understood. The jumps will occur every time you get a new "Simulation" from the gauge based on the the conditions the pack is current in. I recommend you take a Relax, Discharge, Relax test run though…
